Precision Engagement Restoration for GD STI & "Golden Era" Builds.

For the "Golden Era" GD STI, the clutch system is a masterclass in tactile feedback—provided the hardware is healthy. Decades of launches and thousands of heat cycles often leave the original clutch fork pivot and springs tired, leading to a "vague" bite point or an annoying squeak.

The Roo Racing 2003-2007 Master Kit addresses the specific hardware needs of the earlier 6-speed manual transmissions. We focus on the high-wear "friction points" that are often ignored during a standard clutch swap. By replacing the entire actuation stack, you eliminate the mechanical slop that ruins the connection between driver and machine.

The Roo Racing Difference:

• Restored Bite Point: By replacing the Release Shaft and Spring, you eliminate the minute "play" that develops in the linkage, sharpening your launch and shift consistency.

• Critical Hardware Refresh: Many builders try to reuse the Shaft Retaining Bung, only to find the 10mm hex is rounded or the seal is gone. We include a fresh Genuine Subaru 10mm Bung as standard.

• Structural Integrity: Reusing an old clutch fork with a heavy-duty "stage 2" clutch is a gamble. Our Genuine Subaru Fork is factory-fresh and ready for the increased stress of performance driving.

• Environmental Protection: Includes the specific GD-chassis Clutch Boot to prevent moisture from entering the transmission housing and corroding the input shaft splines.
